Calcium Filler Masterbatch
Cost-effective calcium carbonate loading for PP and PE applications.
Calcium Filler Masterbatch cuts material cost without changing the line. A share of the virgin polymer in your compound is replaced with a mineral filler, calcium carbonate, that is carried in pellets matched to your resin. The masterbatch is dosed at the hopper just like a colour or additive, so no equipment changes are needed.
The LLDPE grade is formulated with high-purity calcium carbonate and performance additives, delivering excellent dispersion and stable extrusion for blown film and packaging applications. Recommended loading varies by application and is shared per grade. Low moisture content supports consistent film quality and higher output.
2 grades
Two grades, one for each carrier resin.
Tell us your host resin and the application, we will confirm the right grade and a starting loading on a trial run.

Applications
Frequently asked questions
What loading rate should I use?
It depends on the application and the properties your part has to hold. The typical industry range is 10 to 30 percent by weight of the final compound. Lower loadings suit film and high-clarity work, higher loadings suit injection moulded parts and woven products. We recommend a short trial on your line to settle on the right dose for your specific resin and tooling.
Which polymers does it work with?
We supply two grades. The PP grade is for polypropylene-based lines, the PE grade is for polyethylene-based lines. Pick the grade that matches your host resin and the carrier will melt together with your line resin cleanly.
How does it affect the finished part mechanically?
At normal loadings, a properly coated calcium carbonate filler disperses cleanly and the trade-off in mechanical properties is small. Stiffness usually goes up, impact and tensile come down slightly. For higher loadings, our Modifier Polybooster W coupling-agent masterbatch can be used alongside the filler to maintain mechanical properties.
What is the standard packaging?
Standard packaging is in laminated bags suitable for industrial handling. Exact bag size is confirmed at the quote stage to match your warehouse layout and dosing setup. Bulk bag options are available for converters running on tonne pricing.
What is the shelf life and how should I store it?
Stored in sealed original packaging in a cool, dry warehouse, the product remains usable through normal industrial storage windows. Reseal opened bags between uses to avoid moisture pickup, which can affect dispersion.
Can I get a trial sample?
Yes. Tell us your host resin, target loading and the end application, and we ship a matched grade for line evaluation with a Certificate of Analysis. Sample shipping is free within India, export samples are available with freight at cost.
